ieit known that l, Cans, a citizen of the United Stat-es, and av resident of Newton, in the county of lliiddlesex, 'coninioniveath of lliassachusetts, have invented an lniproafement in Separable Fasteners, of which the following description, in connection with the accompanyingdrawings, is al spccilication, like characters on the draw# ings re)resenltine,` like parts.

rThis invention pertains to improvements in separable fasteners. .it is among the obof the invention tofprovifle a separable fastener of inexpensive construction having superior hold. power and which may be, if desired, relatively thin.

` In ,the drawings, Which show a preferredform of one embodiment of my inventiom- Figure l is a ,front elevation of two pieces of fabric, one carrying the stud member and` the other the socket member of a preferred form of separable fastener;

` Fig. asection on the line 2 2 of Fig. l; 4 1

Fig. 3 is a front elevation of the preferred `form of socket member; and

Fig. el. is a front elevation of thepreferred form of stud member. A Referring to .the drawings and Ito the preferred form yof myinvention selected for illustrative purposes, have shown a vstud including` a head 5, a neck 6 and a baseportion 7 secured to the stud-carryingN fabric 8 in any suitable way, but preferably as indicated by stitching 9. The head and neck of the stud are preferably out of center of the base of the stud, as best shown in Fig. 4, the head of the stud being located in the line of strain between Stud and socket` such line of strain ordinarily being perpendicular to and toward the edge of the stud-carrying fabric 8.

The preferred form of socket illustrated may be and preferably is., as illustrated,

formed from sheet metal to provide a stud-` receiving aperture l0 surrounded by a plurality of stitch-receiving openings 11,

these openings preferably beine' connected with the stud-receiving` aperture by slots 12. At one side the socket is preferably completely slotted through as` at 13, and this side, which is preferably located adjacent the edge of the socket-carrying fabric 14, need not be provided-With any stitch-rcwe'ivn iieived in Fig'. 3 somewhat belenY a line `between the stitch-receiving openings at each' side'of the 'stud-receiving aperture.v The slots conne'ctingthe stud-receivingv aperture with these two stitchlreceivinpj openings may be, as illustrated, in line with the stitch receiving openingsv and, therefore, out of vcenter with the axis of the studsreceivng aperture. l

llfhen stud and socket are secured to their carrying fabrics and subjected'to lateral strain in the direction of the ysection line shoivn on Fig. l, the tipping,- moment" produced'by the resolution of forces between stud and sock at is minimized because lthev ec? centric positioning of the stud relative to its base, and of the stud-receiif'ing aperture rel` attive to the socket as' a Whole,provides1a leverage unfavorable to tipping movement,

especially'where all ora greater'part 'of the attachments of the fastener parts totheir carryingfabrics reS-pectivelyk areflocated as indicatedA on those' portions of the fastening elements furthest removed fromthe margins of their respective carrying 'fabricsif 1gllhilelhave shown and `described a pre- "ferred form of. one embodimentzof myinvention, it will be understood that changes involvingy omission, substitution, alteration and reversal of parts, and even changes in the Inode of operation, may be made Without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A separable snap fastener comprising, in combination, a stud having' a head, a neck and a 4base portion, and a socket including a relatively fiat spring portion having a stud-receiving and `retaining aperture at one side of the center thereof. said spring` portion having openings therethrough permitting stitching of the socket to its carrying fabric.

2. A separable snap fastener comprising, in combination, a stud having a head, a neck and a base portion, and a socket including a relativel at sprinov Jortiony havin@ a y L La t-i stud-receiving f and retaining aperture at one side of the center thereof, vsaid spring portion having openings therethrough permitting Vstitching of the socket to its carry-" ing fabric and `slotsr extending from said y il.' A separable `snap fastener comprising,.

in combination, a stud having a head, a neck and a base portion7 and a socket including a relativelyflat springl portion having a stud-receiving aperture' at one sideof the centerthereof, said spring portion having kvopenings therethrough permitting stitching of the socket to its carrying fabric, vslots extending from said stitch-receiving-openings tov said stud-receiving aperture, and a. slotv rfrom said stud-receiving aperture through the periphery of `said flat spring portion.` i

5. A separable snap fastener comprising,

` in. combination, a stud having a head,a neck and `a base portion,'said` head of said stud at one' side kof the central portion of said base portion, and a socket including a relatively flat spring portion having a stud-receiving and retaining'l aperture atV one side ofthe center thereof, said spring portion having openings therethrough permitting stitching of the socket toits carrying fabric.` "6. -A separable snap fastener comprising, in combination, a'stud having a head, a neck anda base portion,said head of said stud at one side of the central portion of aperture.

said base portion, and a socket including a relatively fiat spring portion having a. studreceiving and retaining aperture at one side of the center thereof, said spring portion having openings therethrough permitting stitching of the socket to its carrying fabric, and `slots extendingfrom said stitch-re ceiving openings to said stiid-receiving 7. A separable snapA fastener comprising, in combination, a stud having a head, a

neckv and a base portion, said head of said' stud atene side of the central portion of said. baseA portion, and a socket including a relatively flat spring portion having a stud-y receiving and retaining aperture at one side of. the center thereof, said spring portion having openings .therethrough permitting s ititchingy of the socket to its carrying fabric, and a slot from said'stud-receiving aperture through the periphery of said.- flat spring portion.r

8. A socket for separable snap fasteners formed froina fiat sheet and presenting a stud-receiving aperture, a slot from said ,l

aperture to the periphery of the socket, a plurality of holes `through said socket, and

slots connecting said holes and the' stud-receiving` aperture, the` periphery of said socket indented to provide generally con- ,y

stant cross-sections about the exterior sides of said holes. t 4

9. A socketfor separable fasteners formeel from a flat. sheet and presenting a stud-receiving aperture, a slot froin said aperture to the 'periphery of the socket, a plurality of holes through said socket-` and slots connecting said ,holes and the stud-receiving aperture, said stud-receiving,aperture located out of centervofsaid socket and nearer the side thereof having a slot extending to the periphery than to the opposite side thereof.

In testimony whereof, I have signedmy naine to `this specification.
